IOS ReplayKit RPScreenRecorder 的屏幕录制功能

IOS ReplayKit RPScreenRecorder 的屏幕录制功能

开始录制有两个方法:

• (void)startRecordingWithMicrophoneEnabled:(BOOL)microphoneEnabled handler:(nullable void(^)(NSError * _Nullable error))handler);

• (void)startRecordingWithHandler:(nullable void(^)(NSError * _Nullable error))handler);

第一种可以录制屏幕和声音，第二种仅能录屏。调用会弹出弹出框

结束录制：

• (void)stopRecordingWithHandler:(nullable void(^)(RPPreviewViewController * _Nullable previewViewController, NSError * _Nullable error))handler;

结束录制的回调中有一个previewViewController，该参数包含录制的屏幕视频预览图，顶部的返回和保存，以及底部的分享。 一般，我们只需要 present 出这个 ViewController。然后，点击保存就会自动存入相册 。也可以点击分享，直接分享到一些第三方。

代码段：

#pragma mark - 开始/结束录制

    if ([RPScreenRecorder sharedRecorder].recording==YES) {
        NSLog(@"已经开始录制");

    }

    if ([self systemVersionOK]) {

        if ([[RPScreenRecorder sharedRecorder] isAvailable]) {
            NSLog(@"录制开始初始化");
            //            [[RPScreenRecorder sharedRecorder] startRecordingWithMicrophoneEnabled:isAbleMic handler:^(NSError *error){
